tipped reinforcement 3

[DoubleStud]

I mostly do residential projects and I love looking at other company/people structural drawing. I see this one detail that I have never seen before on my friend's house. Have you seen or done this before? The reinforcement is tipped? Seems complicated especially at wall corners? This is the typical basement wall drawing and the floor framing is not shown. What do you think?

I know it's allowed, I just don't remember seeing it very often outside of an architect's IRC prescriptive drawing. Personally 10" or thicker we've always done two layers.
